When its been running Prime 95 for 24 hours it does lol. First 2 hours of prime 95 it was at 72 max. Generally I Idle around 35-38 and hit mid 40's when I'm gaming. The Last 6 or so hours it was jumping up to 80 for a little bit. My corsair fans were on medium as well though after I set it to high it brought the max back down to 72-75.
